I sketched out a couple ideas and landed on it being a little frog floating down the river. I have a vision of it spinning around on lily pad and then bumping into another frog that gets knocked into the water. Then, the frog will be pulled up onto the same lily pad and they will float off together.

I also drew the background that will be just rolling on a layer transform the whole time. I'm not sure if that's the most.... efficient way to do this but oh well!
